Provided is an energy storage dye-sensitized solar cell having a simple structure. An energy storage dye-sensitized solar cell of the present invention has a photoelectrode and a charge storage electrode on the same surface of a conductive substrate such that the photoelectrode and the charge storage electrode act as one electrode. Hence, the energy storage dye-sensitized solar cell comprises two electrodes: the above-described one electrode and a counter electrode covered with a catalyst, thus having a simple structure.
